CB-7021, CB-7022, CB-7024 User’s Manual
The CB-7021/21P/22/24 provides programmable slew rate
control. When an output command is sent to CB-7021/21P/22/24
to change the analog value, the output automatically drives to the
new value at the specified slew rate. The CB-7021/21P/22/24
updates the analog output value at 100 conversions per second.
The programmed slew rate sets the value of each 10 ms step change.
Thus, the output is smoothly stepped until the final output value is
reached. Refer to the specifications for the minimum and maxi-
mum slew rates.
3.7 Current Readback
The CB-7021/21P/22 have an analog-to-digit converter to
monitor the current output signal. The current readback will
indicate an open wiring or load when the readback value is far from
the transmitted output value.
The CB-7024 does not have the analog-to-digit converter
to monitor the current output signal. But, the CB-7024 can returns
the current digital value transferred to the DAC.
NOTE: The CB-7024 can’ t read the actual DAC output
current value , thus can’t detect faulty wiring or loads.
